Maximiser should in its default way, not affect wow in any TOS breaching way.

It honestly sounds like you made a whoopsie with either another program, or were somehow using the programs you have at the moment in a way that was actually breaching the tos.
Considering how many people actually use maximiser for window location, and the fact that this is the first I heard of this, it really does sound like the normal maximiser and keyclone use were not the cause.
